While the code gets more complex, the new query will first filter all relevant RfCs and only use the `with_last_activity` scope for the current page.
Using `distinct` in the policy is not required (no duplicated RfCs), but causes issues for the ordering otherwise. Therefore, it is removed.
Fixes CODEOCEAN-J2
Previously, we were always fetching files, even if not required (e.g., for score runs). Now, we reduce the number of file listings and use a dedicated callback.
Previously, an exception was caused by the tubesock gem but not sent to Sentry. This caused errors not to bubble up correctly but rather kill the current thread, leaving the user with a generic "WebSocket connection not established" message.
Probably, this should be removed when updating the WebSocket implementation.
When a file cannot be retrieved any longer, we send a redirect to the previous locations. As we usually enable a different render host, Rails sees this redirect as a redirect to another host (from the render host to the main CodeOcean host).
An invalid XML response may be returned if the LTI provider is unavailable and cannot handle our request. We decided against logging in Sentry as this affects a third party functionality we cannot fix ourselves.
Fixes CODEOCEAN-G2
Also align how we use query Postgres from controllers.
The change is mainly due to regular (but not reproducible) issues with the `intervalstyle` defaulting to `postgres` (instead of `iso8601`) and thereby causing issues. We're just experimenting to see whether this change resolves the issue.
* Remove `send_stream` method pulled in before upgrading Rails
* Remove spring, it is no longer included by default for new apps
* Remove deprecated options from environments
* Remove old asset paths and workarounds no longer needed
* Remove unnecessary `OAUTH_10_SUPPORT` const, LTI still uses OAuth 1.0
* Dump schema with new defaults (and specify precision for timestamps where needed)
